It is undoubtedly true that development rarely takes root without security; it is also true that security does not exist where human beings do not have access to enough food, or clean water, or the medicine and shelter they need to survive. It does not exist where children can't aspire to a decent education or a job that supports a family. The absence of hope can rot a society from within.
And that's why helping farmers feed their own people -- or nations educate their children and care for the sick -- is not mere charity. It's also why the world must come together to confront climate change. There is little scientific dispute that if we do nothing, we will face more drought, more famine, more mass displacement -- all of which will fuel more conflict for decades. For this reason, it is not merely scientists and environmental activists who call for swift and forceful action -- it's military leaders in my own country and others who understand our common security hangs in the balance.
Agreements among nations. Strong institutions. Support for human rights. Investments in development. All these are vital ingredients in bringing about the evolution that President Kennedy spoke about. And yet, I do not believe that we will have the will, the determination, the staying power, to complete this work without something more -- and that's the continued expansion of our moral imagination; an insistence that there's something irreducible that we all share.
As the world grows smaller, you might think it would be easier for human beings to recognize how similar we are; to understand that we're all basically seeking the same things; that we all hope for the chance to live out our lives with some measure of happiness and fulfillment for ourselves and our families.
And yet somehow, given the dizzying pace of globalization, the cultural leveling of modernity, it perhaps comes as no surprise that people fear the loss of what they cherish in their particular identities -- their race, their tribe, and perhaps most powerfully their religion. In some places, this fear has led to conflict. At times, it even feels like we're moving backwards. We see it in the Middle East, as the conflict between Arabs and Jews seems to harden. We see it in nations that are torn asunder by tribal lines.
And most dangerously, we see it in the way that religion is used to justify the murder of innocents by those who have distorted and defiled the great religion of Islam, and who attacked my country from Afghanistan. These extremists are not the first to kill in the name of God; the cruelties of the Crusades are amply recorded. But they remind us that no Holy War can ever be a just war. For if you truly believe that you are carrying out divine will, then there is no need for restraint -- no need to spare the pregnant mother, or the medic, or the Red Cross worker, or even a person of one's own faith. Such a warped view of religion is not just incompatible with the concept of peace, but I believe it's incompatible with the very purpose of faith -- for the one rule that lies at the heart of every major religion is that we do unto others as we would have them do unto us.
Adhering to this law of love has always been the core struggle of human nature. For we are fallible. We make mistakes, and fall victim to the temptations of pride, and power, and sometimes evil. Even those of us with the best of intentions will at times fail to right the wrongs before us.
